in relation to solids or liquids in liquids:
Density. A lighter density compound/liquid will float in a heavier density liquid
Objects float because the air in the object causes it to rise because it is less denser than water. Objects float better in salt water because the salt makes the water more denser helping even heavier objects to float. -Kimberly P.S. I learned all this in 4th grade!!!!!!!!!!!

Buoyancy is the force that causes things to rise or float in a fluid, such as water or air. This force is exerted in the opposite direction to the force of gravity, making objects appear to be lighter when submerged in a fluid.
Give a higher density to the water due to the salt content which causes object to float higher.
Objects float in space because there is no gravity to pull the objects down. While on earth there is gravity so it pulls the objects to the ground.
Objects that are denser than water will sink, such as rocks, metal objects, and certain types of wood. Objects that are less dense than water will float, such as plastic bottles, rubber ducks, and foam.
Objects that are less dense than the environment in which they are immersed will float, unless they are tethered.
Objects that float in water have a lower density than water. -anonymous18_K
Objects that are less dense than the environment in which they are immersed will float, unless they are tethered.
Because some objects are a lot denser than water so the sink and others are less denser so they float
objects that are less dense float to the top.
Hot liquids have lower density than cooler liquids because the heat causes the molecules to spread out, making them less dense. This difference in density causes the hot liquid to float above the cool liquid because objects with lower density float on top of objects with higher density.
